Aluminum is one of the most used metals in today’s society – Extruded Aluminum Sliding Door Track in Guide it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.
The manufacturer will begin by removing the aluminium from deep within the earth’s crust (either as bauxite ore or feldspar). Often, the Bayer’s method, Wohler’s method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, Aluminium Window Frame Extrusions it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.
Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.
The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.
Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, Flat Aluminum Extrusions the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.
Extruded Aluminum Sliding Door Track in Guide?
Aluminum is a non-ferrous metal (which means it will not draw a magnet) that is lightweight. There are several different grades of scrap aluminum, and all of them vary in price. At most scrapyards, aluminum is broken down into the following grades:
Radiators (clean and contaminated)
Extrusions (clean and contaminated)
Wheels (Clean and Chrome Plated)
Aluminum/Copper Radiators (clean and contaminated)
Cast aluminum is very brittle and when broken, the inside will appear very grainy. A majority of the cast aluminum that comes across our scale is from auto parts. Transmission housings, engine cylinder heads, and electronic covers are all examples of cast aluminum auto parts. Other miscellaneous items that are made of cast aluminum include BBQ covers, some hot plates and skillets, and some light housings.
Aluminum radiators can be brought to our yard in two forms, contaminated or clean. A clean aluminum radiator must have all tanks, hoses, and steel and plastic removed. The plastic tanks on each end of the radiator will typically contain steel, sometimes however they will contain a tube made of aluminum or brass.
Extrusion is the process of pushing material through a die to give it a particular shape, very much like a Play-Doh spaghetti machine. The most common form of aluminum extrusion we see is window frames, but it is used very often in other framing systems and structural applications. Extrusions are broken down into contaminated and clean grades, with clean extrusion containing no steel, plastic, rubber, or insulation.
Aluminum Wheels come in two varieties, aluminum and chrome plated aluminum. Chrome plated wheels are worth a little less than pure aluminum due to the chrome contamination. Wheels with plastic face covers are also considered chrome plated due to the contamination of plastic and glue. Our listed wheel price assumes wheel weights, valve stems, and center caps are still attached. If these have been removed from your wheels discuss it with our scale operator and he may be able to increase your price.
Aluminum siding also includes gutters, downspouts, and other flat stock aluminum items. To receive the aluminum siding price, the material must not contain steel, Styrofoam, tar, insulation or any other contamination.
Aluminum/copper radiators are found in air conditioning units. They are copper tubes surrounded by aluminum fins. A clean aluminum/copper radiator will contain no steel flanges. If the steel flanges are cut off of a dirty aluminum/copper radiator, the rest of the radiator can be sold as clean and the flanges can be sold as aluminum breakage if they still contain some aluminum and copper.
Old sheet is the lowest grade of scrap aluminum and just about everything that has not been mentioned so far falls into this category. Some common aluminum sheet items include pots and pans, pop cans, lawn chairs, and screens. Siding containing excessive Styrofoam or tar will also be bought as aluminum sheet.
Aluminum Frames Vs PVC Or Wood - Are They Worth the Extra Cost?
In our past articles I talked about all the steps required to properly replace your old wood sash windows with energy efficient vinyl windows. I told you how to measure for the new windows. Then we discussed the removal of the wood sashes and parting bead. Finally, I told you how to install, seal, and trim the vinyl replacement windows. But, what if those old windows in your home are made of aluminum instead of wood? Is the process the same? No, it's not the same at all. So, the next few articles are going to explain the differences between replacing wood windows versus aluminum windows.
When discussing the proper frame style for replacing the wood sash windows, I explained the difference between new construction frames versus replacement frames. When replacing aluminum windows, there is another option we have to consider regarding frame style. It's called a "retrofit" frame. Let's go over each frame type. First, we have the new construction frame with the nailing fin. If you choose to go this route, you have to remove the exterior around each window opening, pull out the nails holding the aluminum window to the studs, nail in the new vinyl window, apply flashing, caulk, and re-install the exterior around each window.(I get tired just talking about it!)In addition to being a whole lot of labor, you can run into major problems trying to install the exterior product around each window opening. If your home has stucco, you have to try and match the rest of the stucco. It can be done, but not by you. Even most professional stucco guys can't get a perfect match. What if you have wood siding? Well, you can cut away 2" of the siding around each window to get to the nail fin, then you can apply 1 X 2 or 1 X 3 trim around each window. Certainly not as much work as the stucco home, but probably more work than the average homeowner cares to tackle. What if each window is surrounded by brick? Let's not even go there! You would have to remove the bricks, then re-install them all when finished.
Trust me, you don't want to replace your old aluminum windows with new construction vinyl windows. You want to use either the replacement frame like the one used to replace the wood sash windows, or something called a retrofit frame, that is popular in the west where stucco is a common exterior. Since the procedure for measuring is the same regardless of the frame style chosen, this article will discuss the proper measuring procedure, and future articles will explain the difference in the installation process for replacement versus retrofit.
If you look at the portion of the aluminum frame that goes around the window opening into your surrounding walls, you will see three separate "legs" that form two pockets. The outside leg and the center leg form the first pocket. Your screen and stationary panel will be in this pocket. The center leg and inside leg form the second pocket, and your sliding panel is in that pocket. Find the "leg" that is the widest on all four sides. When measuring the width, run your tape measure from the widest leg on the left to the widest leg on the right. This should be the narrowest measurement. Then, subtract 3/8" from that measurement. This is the width of the replacement window. Measure the height the same way. When measuring the height, measure as close to the center of the window as possible. This is especially important on windows wider than six feet, because the top wood header has a tendency to sag over time, making the center of the opening the narrowest. You don't need to deduct 3/8" from the height like you did on the width. 1/4" is fine. These are the dimensions you use when ordering your vinyl window. If you have any picture windows(windows without a vent panel), there will only be two legs and one pocket. You still measure the same way.
Next week I will discuss whether your home is a candidate for retrofit frames or replacement frames...
